CPackIFW: add support for archive format and compression level options

Adds the following CPackIFW variables:

- CPACK_IFW_ARCHIVE_FORMAT
- CPACK_IFW_ARCHIVE_COMPRESSION

These variables control mirror the --archive-format and --compression
options of the QtIFW binarycreator and repogen tools.

Fixes: #22803
